To all whom it may concern:

Be it known that I, ROBERT HENRY, a citizen of the United States, andresiding in Pueblo, county of Pueblo, and State of Colorado, haveinvented a certain new and useful Improvement in Metallic Brushes, ofwhich the following is a specication.

My invention relates to improvements in metallic brush devices, and theobjects of my invention are ;--to provide Wire bristles which are soarranged that each bend of wire is provided with a double spring forreverse action, said wire bristles are so constructed as to present onlybent portions of the wire on the surface of the brush. I' attain theseobjects by the means illustrated in the accompanying drawings, in which-Figure 1 shows perspectively and in partial broken section the block orfoundation with wire spring bristles attached; Fig. 2 is a top plan viewshowing the arrangement of the tops of the wire springs; and Fig. 3 is abottom plan view of the attachment of the springs to the block.

Similar numerals refer to similar parts throughout the several drawings.

Block 24 is provided with slots 5 on the bottom and perforationsextending from the top to the bottom connecting with slots 5. The wire lat the top is bent in the form indicated and at 2 is wound from left toright giving a spiral spring coil and at 3 is wound forming a coil inthe opposite direction. In any one set of said spiral springs thespirals are wound in opposite directions, and below the spirals 2 and 3the wire is bent in the form of a loop as shown at 4 f1tting into aperforation from top to bottom so that a wire 6 may be run through thelower end of loop 4 in slot 5 thereby binding the formed wire downfirmly to the top of block 24. When a series of wires are thus formedthey may if desired be placed on the block diagonally as shown in F ig.2. The interlocking of wire 1 which forms the wire bristles to the block24 is shown in bottom plan View, Fig. 3.

By the bending of wires to form the bristles as stated above a smoothsurface is furnished and at the same time the several coils in each wiregive the desired flexibility for the Wires forming the bristles toreturn to their fixed positions in whichever direction they may bepressed upon. By the method I have provided for attaching the bristlesto the block 24 any row of bristles may be easily removed or a portionthereof and a new row or portion of a row replaced. I have avoided theuse of pointed wires by this means and have also furnished a sanitarybrush.

It will thus be seen that the brush which I have provided is usableWherever it is desired that a surface shall be cleaned Without danger ofscratching on the sharp points or ends of wires, and at the same time Ihave arranged a means of attachment to the brush block whereby the sameis readily repaired and at the saine time the coils in the wire beingreversed on each side of the surface loop resiliency is given formovement of the bristles in either direction.

I claim In a metallic brush of the character described, a series oflooped surfaces on the usable side formed of bent wire, two coils witheach of said looped surfaces, a loop in said wires for engagement withblock, key means of locking the wires in the base block, a base blockcarrying perforations to receive said loops for engagement and channelsfor key means, all substantially as set forth.

ROBERT HENRY.
